Modding, i just wanted to say that though we all have an unwavering adoration for these phones that have given us so much strife, health and well-being should still be a priority. So if at any point you start to feel slightly annoyed, a little upset or suicidal, it's only phone and you can stop at any point.
That said, your kernel is really awesome and all your hair-pulling has paid off in 99% of the things you've tried (and shown us). Eff those KGSL drivers, we didn't need 'em anyway.
Hmm i've always been a little annoyed about this. Unfortunately there's nothing we can really do (that i know of). If you bump up your lcd density to like 340, the icons would become less blury cause android would assume your screen is a high resolution and therefor requires higher resolution icons, but the phone becomes a little unusable at this screen density.
Anyway, i feel your pain bro :(
For those that are interested in a bigger g510 battery: http://www.ebay.co.uk/itm/High-Capacity-HB4W1-for-HUAWEI-Y210-T8951-U8951-G510-2300-mAh-Mobile-phone-/141326674857?pt=LH_DefaultDomain_3&hash=item20e7b9eba9
1) nope, android L is really only out on nexus devices at the moment, afterall, it's only a developer preview
2) i don't believe anything has changed in the kernel for a quite a while, so there really wouldn't be any benefit to doing that. If you want to install synopsis or chil's kernel, then yeah you ca flash those over top, and just wipe cache and dalvik
